Usage

    const csv = require('csv-for-you');
    const parseOptions = {
        arraySeparator: '|', // not required, default value is ';'
        objectSeparator: '^', // not required, default value is ';'
        lineAsArray: false, // not required, default value is 'true'
        fileAsArray: true, // not required, default value is 'true'
        returnAsString: ['name', 'ID'], // not required, default value is an empty array
        innerCallbacks: true, // not required, default value is 'true
    };

    const addOptions = {
        lineNumber: 0 // not required, default value is 0 (deletes first line)
    };

    const deleteOptions = {
        rowNumber: 5, // required! default value is -1
        rowsToDelete: 3 // not required, default value is 1
    };

    const editOptions = {
        data: { name: "john smith", age: 77 }, // required! must be an object
        lineNumber: 3 // required! must be an integer and bigger than 1
    };

    async function myFunction() {
        const myCsvFileData = await csv.parse('C:\\path\\to\\my\\file.csv', parseOptions, { lineCallback: yourLineCallback, objectCallback: yourObjectCallback } );
        // Use the data however you'd like
    };

    csv.addRow('C:\\path\\to\\my\\file.csv', { name: "john smith" }, addOptions );
    csv.editRow('C:\\path\\to\\my\\file.csv', editOptions );
    csv.deleteRow('C:\\path\\to\\other\\file.csv', deleteOptions);

The parse options object

This object contains the parse function options. 1) arraySeparator - the Char that represents the separator between Array elements 2) objectSeparator - the Char that represents the separator between Object elements 3) lineAsArray - Boolean that represents rather a line should be represented as an Array or Object 4) fileAsArray - Boolean that represents rather the file should be represented as an Array or Object 5) returnAsString - Array of property names that should be returned as a string 6) innerCallbacks - Boolean that represents rather value callbacks should be implemented if there is a callback for the line/file

Features

1) Parses strings in CSV 2) Parses numbers in CSV 3) Parses arrays - numbers, strings, arrays and objects 4) Parses objects - numbers, strings, arrays and objects 5) Add data with the addRow function 6) Delete data with the deleteRow function 7) Edit line with the editRow function 8) callbacks - you can pass a custom callback function for each line and type of value

CSV file format

1) Properties - The first line of the file must be the properties of the objects 2) Numbers - Any integer or float number 3) Strings - Strings of any length 4) Arrays - Must start with [ and end with ] while the separator is not ,(arraySeparator in the options object to change) 5) Objects - Must start with { and end with } while the separator is not ,(objectSeparator in the options object to change) 6) Values are separated by ,

Future features

1) Parsing text to JSON 2) Fetching data from servers using URL 3) Reading file structure starting from a folder 4) Creating a CSV file from JSON object 5) Error notifier - Lets you know what is the problem 6) Generating numeric data to CSV or JSON 7) Generating lingual data to CSV or JSON
